Abstract
A ground plane element in a channel has a width slightly less than the channel width, thus forming a ridge mode waveguide. Means such as conducting strips are used to suppress the ridge mode. The strips are preferably corrugated for good contact and to firmly secure them. The suppressing means can prevent bypassing a microwave low pass filter.
